ISPConfig 3 Security Advisory

Summary

A security issue has been found in the sites module which allows customers to create website users for websites which they do not own from within the ISPConfig interface.

This issue requires a valid ISPConfig client login and the manipulation of http variables.

If a client would try to create a login for a different site, his actions are recorded in the sys_datalog and can be tracked down by the administrator even if he deletes this login again.

Affected versions

All ISPConfig 3 versions < 3.0.5.3

Mitigation

A hotfix for ISPConfig 3.0.5.2 is available at ispconfig.org:

http://www.ispconfig.org/downloads/ispconfig-hotfix-2013-08-08.zip

This hotfix needs to be applied only to servers with an ISPConfig interface; you do not need to apply this patch on slave servers without an ISPConfig interface.

Installation instructions for the hotfix:

Login to your server as root and execute the following commands:

wget http://www.ispconfig.org/downloads/ispconfig-hotfix-2013-08-08.zip
unzip ispconfig-hotfix-2013-08-08.zip
cd ispconfig-hotfix-2013-08-08/
chmod +x ispconfig-hotfix.sh
./ispconfig-hotfix.sh

Additionally to the hotfix, ISPConfig 3.0.5.3 will be released tomorrow
(August 09. 2013) which fixes this issue as well.
